Power5 End of Support & Risk
What IBM's staged Power5 end-of-support withdrawals actually mean, and what running unsupported hardware exposes an organization to.
IBM phased out standard hardware maintenance and lease/rental services for Power5 systems in stages, by machine type, between January 2019 and October 2020, roughly 15 years after the line launched. The exact date depends on your specific machine type and feature code; if you need the precise date for your unit, IBM's own withdrawal-announcement documentation for that machine type and IBM's support pages are the source of record.
What "end of support" actually means
What stops, and what keeps running
| Area | Status |
|---|---|
| The hardware itself | Keeps running exactly as before, IBM's support ending doesn't shut anything off |
| IBM hardware maintenance contracts | No longer available new from IBM for this hardware; only third-party maintenance remains |
| Microcode and firmware updates | IBM no longer issues them for this hardware |
| IBM i software support | IBM i itself has its own separate release support lifecycle, largely moot here since Power5 hardware cannot run any current IBM i release |
| Security patching at the OS level | Effectively frozen at whatever release the hardware's IBM i ceiling allows |
The real risk
The practical risk isn't a single event, it's compounding exposure: a hardware failure with no IBM parts pipeline behind it, an IBM i release so old it can no longer run current software or receive security fixes, and, for regulated environments, a genuine compliance gap if an auditor asks what your disaster-recovery and patching story looks like on 15-to-20-year-old, unsupported hardware.
